My little Marlin 1894 in 357 has a nasty little problem of allowing the primer crater around the fireing pin to strick up. It is not a real problem until I start pushing the pressures up to book max then they actualy pierce a hole to the exact shape of the stick up. I am not "hot" loading and the primers show round profile on the edges, not flat or sharp. I can load the 44 lever gun up to book max with no sign of this and have never had any other gun do this either. Any ideas out there on what may be allowing or causing this to happen??
